Perfect spark.
Good old traditional spark plug made by Champion. Works great, but had to adjust gap for my lawnmower.

Reliable Spark Plug for Small Engine Maintenance
This Champion RJ19LM spark plug is the recommended replacement for my Craftsman lawn mower model 917.376651. Installation was simple, and the plug worked as expected. I noticed an immediate improvement in engine performance. This quality spark plug offers great value for keeping a small engine running smoothly.

High quality. Not made in China.
The right product for the job. My mower runs well again. It's nice to buy a product not made in communist China.

Perfect fit in go cart but having issues now
I have a go cart that’s a little older. It was well cared for and ran on the same plug for a few years. I decide to buy a new one and change oil, etc. the first pull this started right up and I swear it had a little more power. However after we ran it 2 times for around an hour I’m having trouble getting spark. Not sure it is the plugs problem but that’s the only thing I’ve changed. Will likely buy another and see if it’s the plug. Easy to install, good price point. I adjusted the gap but it didn’t seem to matter after I replace this one I will update this review and note if I am having same issue with new plug or if it’s something else.
